Abstract
A light collection device includes a light guide body and a plurality of spaced-apart slits. The slits are formed by undercuts in the light guide body. Sides of the slits form facets that redirect light impinging on the facets. In some embodiments, the light collection body is attached to a photovoltaic cell. Light impinging on the light collection body is redirected towards the photovoltaic cell by the slits. The photovoltaic cells convert the light into electrical energy.
